How does the double-and-add algorithm optimize the computation of scalar multiplication on an elliptic curve?

The double-and-add algorithm is a fundamental technique used to optimize the computation of scalar multiplication on an elliptic curve, which is a critical operation in Elliptic Curve Cryptography (ECC). Scalar multiplication involves computing , where is an integer (the scalar) and is a point on the elliptic curve. Direct computation of by repeated addition is

In EC starting with a primitive element (x,y) with x,y integers we get all the elements as integers pairs. Is this a general feature of all ellipitic curves or only of the ones we choose to use?

In the realm of Elliptic Curve Cryptography (ECC), the property mentioned, where starting with a primitive element (x,y) with x and y as integers, all subsequent elements are also integer pairs, is not a general feature of all elliptic curves. Instead, it is a characteristic specific to certain types of elliptic curves that are chosen
